SEP 28 '93 01~26PM CYPRUS HRNNR P.3 <br />• • <br />Z.0 MAPS <br />The attached map, Foidel Creek Mine, Subsidence Monitoring Status Map, illustrates the <br />following information: <br />1. Location of subsidence monuments; <br />2. Extent of existing underground workings with monthly longwall advance for <br />this report period as well as the extent of all underground workings to date; <br />3. Current mine plan; and, <br />4. Surtace topography end structures. <br />The following subsidence cross-sections are attached: <br />Subsidence Line 1000 <br />Subsidence Line 3000 <br />Subsidence Line 4000 <br />Thase cross-sections illustrate monument location, subsidence for this report period, and <br />total subsidence to date for each monitoring line. <br />3.0 STRUCTURES <br />The identified structures located in the current subsidence area are shown on the <br />attached map. <br />4.0 CONCLUSIONS <br />This section summarizes the results and conclusions from the subsidence monitoring far <br />this reporting period. <br />The data used to generate the subsidence cross-sections are tabulated in the following <br />tables: <br />Subsidence Monitoring Data, Monitoring Line 1000 <br />Subsidence Monitoring Data, Monitoring Line 3000 <br />Subsidence Monitoring Data, Monitoring Line 4000 <br />The Appendix summarizes monitoring dates during this reporting period and presents the <br />original field data, In review the field data, the subsidence monument number is listed in <br />the Descriptor column followed by the survey date. <br />It should be noted that undermining of the 3000- and 4000-lines was completed in <br />January 1993. The final monitoring survey for this report period was conducted in <br />June 1983. It is estimated that subsidence along this monitoring line was more than 959b <br />q9~n iw.,mnh Bw.i~wnuu BuecAe~ FeOOrt <br />~Vd~11, tW! ~ MM1 <br />
